Another question on rear calipers

Posted: Sun Nov 17, 2013 4:32 pm

So following on from the sticking caliper saga (which still aint fixed Embarassed

)..

Were the 'quattro' calipers fitted to the 2wd models at all?

Looking at the calipers on mine (2wd), there's nothing obvious to help me identify them. The only main difference I can tell with these calipers is the presence on a spring externally on the handbrake mechanism.

Spoke on the phone to the guys at Bigg Red when I ordered the seal kit, trying to determine which caliper set I had, Girling or Lucas. I was told Lucas, which I then bought the kit for.

Looking later on on ETKA and the drawing of the quattro calipers has no spring, and is called Lucas by ETKA. However the 2wd calipers do have a spring and are called Girling.

So based on the above, Girling calipers have a spring, Lucas don't, however there's no consistency between which models were fitted to which..

What has everyone else got?

I thought Girling was part of Lucas

I just sold a set of rear calipers for a quattro coupe. They had Girling stamped on them and another set I have are stamped Lucas, yet both sets are identical.

Looking in etka, p/n’s are different between 2wd and quattro calipers
2wd cross over to 80/90/coupe/cab and 100/A6 and 200 but there is a chassis break in there.
quattro calipers cross over to same as above but obviously quattro equivalent

However, I have a set of A6 quattro calipers for 245x10 disc somewhere and I am sure the handbrake mechanism is different

If I get time this weekend I’ll dig them out, see if I can get some more info off them
I may also have a pair of 2wd 80 calipers so I’ll try find them too.

Girling is indeed part of Lucas, but it appears this is the differentiation made between the quattro and 2wd calipers.

I'd appreciate more info, photos if possible - I'll try to take some this weekend as I go about stripping down my troublesome handbrake mech.

Fitting the later a4/passat alloy type is doable

Useful to know - I guess the carrier/hub/axle fittings are all the same size and spacing.

Not sure I'm going to follow this route myself- I've heard stories about the alloy calipers corroding and causing all sort of their own problems (snapping bleed screws is a favourite apparently).
